SIDE BEARING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed June 6, 1919. Serial No. 302,252.

To all whom it may concern Be it known that I, JOHN F. OCoNNoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Side Bearings for Railway-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this spec1fication.

My invention relates to improvements in side bearings for railway cars.

One of the objects of my invention is to provide a simple gravity centering slde hearing. A further object is to provide a body bolster side bearing of simple constructionv having gravity means to return its anti-friction member to normal position. Other objects will appear from the description of the device hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a cross section of a body bolster showing a vertical sectional view of my improved side bearing secured thereto. Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1. Fig. 3 is an end view of one of the pendulums employed in my device.

Referring to the drawings, the numeral 10 indicates a body bolster of a railway car and 11 the bearing plate of an opposed truck bolster. The side bearing includes a retaining or base member 12 having the lugs 13, by means of which the base member is attached to the bolster by the rivets 14.14. The base member is provided with an integral base plate or block 15 and the side walls 1616 are provided at their lower ends with the inturned portions 17--17, forming the tracks 18-18, which are adapted to carry the ends or trunnions of the axle 19 which passes through the anti-friction roller 20 mounted in the base member. In the base plate and at each side thereof are provided the recesses, channels or grooves 21, each to receive the upper end of a pendulum 23. The side walls 16 of the base member are perforated, as at 2t24, for the passage of a bearing plate 25, which is provided at one end with the head 26 and at the other end with a cotter key 27. The said bearing plate forms the lower walls of recesses 28 ofiset from each of the recesses 21 and within which the trunnions 29 of the pendulums 23 are received.

Each of said pendulums is provided with an opening 30 through which the bearing plate 25 passes, the said openings being suitably conformed, as clearly illustrated in Iiig. 3 of the drawings, to permit the swinging of the pendulum about the plate 25. Itach pendulum is provided with a vertically elongated slot 31 through which the agile 19 passes, so that in the assembled device, as illustrated in the drawings, the axle 1t) rests at its ends upon the tracks 18 provided therefor, passes through the openin s 31 in the pendulums 23, which are profs?- ably two in number, having the anti-friction roller 20 mounted between them. The said pendulums are downwardly extendedout of the casing but fall short of engaging the lower bearing plate 11.

In assembling the device, the pendulums and the anti-friction roller are inserted in the base member, the axle 19 is then passed through one of the openings 32 in the side walls of the base member and thus into its position within the roller 20 and dropped into engagement with the tracks 18, whereupon the bearing plate 25 is placed in its positlon through the openings 24 of the side walls of the base member, thus serving as a key to hold the parts in their assembled condition. The normal position of the parts is shown by the full lines in Fig. 1 of the drawings. On the approaching of the bolsters toward each other, and the engagement of the anti-friction roller by the bearing plate 11, the said roller will roll between said bearing plate and the upper bearing plate 25. On movement of the anti-friction roller to the right, it will reach its extreme position, as shown by the dotted lines referenced 33 in Fig. 1 of the drawings, and the axle 19 will be carried with the said roller, and this axle will brin the pendulums 23 also to the right until t ey reach the position indicated by the dotted lines referenced 34 in Fig. 1 of the drawings. During this movement, the pendulums will swing upon their trunnions 29 and about the bearing plate 25, as hereinbefore indicated. Upon the release of pressure upon the roller, the pendulums will, thr return to their normal position and will carry with them, through their draft upon h gravity, tend tothe axle 19 passing through them the roller 20, which is mounted on said axle. In this return movement the axle will move upon the tracks 18 provided therefor.

I claim: 1. In a side bearing for railway cars, in

v combination, a base member, an anti-friction each of said grooves, a key passing through, the base member and supporting said pendulum, an anti-friction roller mounted between the pendulums and an axle extended from said roller and engaging the pendulums.

3. In a side bearing for railway cars, in combination, a base member having a pair of grooves therein, a pendulum in each of said grooves, a key passing through the base member and supporting said pendulums, and an anti-friction roller mounted between the pendulums, the roller being provided with an axle extending from its ends, the pendulums being provided with slots to receive said axle.

4. In a side bearing for railway cars, in combination, a base member having a pair of grooves therein, a pendulum in each of said grooves, a key passing through the base member and supporting said pendulums, and an anti-friction roller mounted between the pendulums, the roller being provided with an axle extending from its ends, the pendulums being provided with slots to receive said axle, the base member being provided with a track to support said axle when actuated by the pendulums.

5. In a side bearing for railway cars, in combination, a base member, an anti-friction roller therein, a pendulum to return said roller to its normal position and a key passing through the base member and supporting said endulum, the said pendulum belng provide with a slot for the loose passage of said key.

6.'In a side bearing for railway cars, in

combination, a base member, an anti-friction roller mounted therein, a pair of pendulums suspended in the base member, an axle extended from the roller and engaged b the pendulums, and a key, the key passing through the pendulums and supported at its ends by the base member.

In a side bearing for railway cars, the combination with a base member adapted to be secured .to the under side of a body bolster and provlded with an upper bearing surface; of an anti-friction element adapted to roll on said bearing surface and the bearmg surface of an opposed bolster; a pair of pendulums pivotally supported from said base member and normally depending vertically, the pendulums being located at opposite ends of said element; and cooperating engaging means on said pendulums and the element arranged to swing the pendulums to a position of unstable equilibrium when the element is actuated, whereby, upon removal of the actuating force, the pendulums wlll automatically return the element to 1ts normal position under the influence of gravity.

8. In an anti-friction bearing of the character described, the combination with a retalning member adapted to be secured to the under side of a body bolster, of an antifriction element associated with said mem- I ber, cooperating means on said member and anti-friction element for normally sustaining the Weight of said element by the retaining member, a gravity actuated pendulum member pivotally supported from said retaining member at a point above the antifriction element, and cooperating means between said pendulum and anti-friction element adapted to swing the pendulum memher to a position of unbalanced equilibrium when the anti-friction element is actuated whereby, upon removal of the actuating force, the pendulum member will automatic- .ally return the anti-friction element to its normal position under the influence of gravity.

In witness that I claim the foregoing I have hereunto subscribed my name this 28th day of May, 1919.
